Last weekend was the first time my wife came to the thought of another man. She was sucking my cock on the bed, when she told me to imagine she was fucked from behind - she even moved her mouth and body as if he was fucking her.

Then she took the vibrator and made herself cum while having my balls in her face, it was so fucking hot! It was also groundbreaking because it was the first time after years of nothing.

Afterwards she said would like to play around with the fantasy of me sharing her - we are still very much at the imagining state.

What would be the next smart move now? I don't want to push her away, so I want to take it very slow.

Is there any good movies we could watch (has to be professional and good productions), games we could play or anything else that plays around the idea but in a slow and controlled environment?
